In victoria suspension and wheel/tyre mods are not a real problem, engineers report is easy to obtain if you want one, we are a vic roads licenced tester, I also worked for a company that done insurance repairs on 4wd's and not once were the insurance company ever interested in what suspension or wheels were on the vehicle.

I expect you spent the festive season hard at work on your project truck and we will have a photo update soon
me I went to Bali for a week of diving, but thats another story.

In my experience most authorised vehicle mods are acceptable across borders so long as you have the approving states paperwork
Here in Darwin its the rego vehicle inspector that signs off on the change, and they dont even change your rego papers for the mod
they just give you a plastic coated card to stick in your glove box
gotta love Darwin
mind you my trucks still rego'd in Qld and I believe ATW's parabolics come with certification, so im fime

Thanks for the info on VSB6 … I didn’t know it existed.

From a cursory reading of that, and what you guys are saying, am I right in thinking I can carry-out virtually any modification I can get approved by a Vicroads authorised engineer?

Are rim width and track increases also more liberal than for cars under VSB14?

Basically, I’m trying to find-out from the mass of experience out there what suspension, brake, wheel and tyre combination is best/cheapest to make a Canter liveable as a long-term home away from home.

I’ve read everything I can lay my eyes on regarding those individual issues, but nowhere have I seen them discussed as ‘a package’.

My primary objective would be soft, long travel suspension either through a longer and possibly re-set spring pack, or the ATW parabolics, and probably a lift to gain ground clearance and accommodate larger tyres.

In taht area, can anyone tell me what level of modifications they know have already been engineer approved?

If you intend to run singles you will probably widen the front track and lessen the rear track in order to have equal tracks front and rear.

As for how big you can go with your wheels and rims... have a look at what Amesz00 intends to run on his latest truck.

Definitely singles, goes without saying.

Yeah, the Amesz00 tyres look impressive (if maybe a little big without some bodywork massaging), but I’m not just asking what can be done physically to improve the truck.

At my age I’m mindful of the insurance pitfalls.

So I’m looking for guidance on the best package of improvements to the Canter which have been legally engineered, preferably with a few pics if they’re available.

Hi Stu, Happy new year!
did a little on the truck but just could'nt get into the groove, Qld seems to be the toughest on vehicle mods, in Vic most mods are ok but if we think something looks dodgey we ask the customer to produce a Engineers report.

When it comes to wheels and tyres, the GVM is a governing factor, legally.

If your intent is to derate the truck to 4.5 tonne then you have quite a few options when it comes to choice of rims and tyres. However, if you plan on keeping the GVM at 6 tonne there are very few singles options.
Alan sells some really schmick 16" alloy rims, in both 5 and 6 bolt patterns. If you were derating your truck then these would be a very nice addition. For a 6 tonne truck, ATW do their SWC using 19.5" rims and Toyo tyres.
There has been much discussion on Expo about the pros and cons of each option (16" vs 19.5"), so I suggest searching the forum if you wish to read people's views on this topic.

As I mentioned initially, the GVM is probably the determining factor when it comes to wheel and tyre options.

Hi Skifreak

We have been advised by QLD transport that downrating the truck to under 4.5T does not alter load ratings required on each axle and that the standard tyre placard still stands true. In our case the minimum rear axle load carrying capacity is 4480KGs even though our GVM is just 4490KGs. We were advised this is the case as Isuzu use same the tyre placard between the NPS 300 and NPS 250. Perhaps its different down your way?

The 4.5T thing is more a drivers licence issue more than load capacity me thinks

That is very interesting.... I did not know that.
This raises the question, how do people get away with fitting something like XZLs then? They do not have that high a load rating for the rear.

If you really want to confuse the transport department / your approved person try pointing out Section 2.0 of Appendix S of the Heavy Vehicle Modification National Code of Practice ( http://www.infrastructure.gov.au/roads/vehicle_regulation/bulletin/pdf/vsb_06_s.pdf ) which states:

Where a tyre placard is fitted to a vehicle, this placard must be replaced or amended to indicate the correct tyre specifications for the vehicle at the revised GVM rating.

I wrongly assumed this meant the tyre placard would be amended to suit the lowered GVM, but QT wouldn't have a bar of it.

Its a QT thing
I derated my SWB FG to 4.5 T so the dragon wouldnt have to get her rigid licence
so now my compliance plate reads GVM 4.495T and GCM unchanged at 10.5 T or close enough
so I can legaly tow a HUGE !!! trailer
like you say so long as the paperwork is in order its all legal

So Stu, does your mod plate specify a revised maximum rear axle load now?

no
its the standard QT blue mod plate with 4.495 scribbled in under GVM, all other data has crosses through it meaning (I guess) refer to the original spec plate
its a strange way of doing things
I would have thought a reduced GVM would afferct the GCM (ie GVM + 4.5T) and therefore automaticaly r4educed the axle load and tyre ratings
mind you I bought my truck during the reign of capt Bligh
when it was cash first - details to follow
